Cut-To-Size Items are Non-Returnable!

As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.

Measure Twice, Cut Once

Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.

How to Use a Measuring Tape

Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.

Features of a Measuring Tape: Sliding End Hook

The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

Cast Acrylic vs. Extruded Acrylic:Acrylic is produced in two basic variations, cast and extruded. Casting and extruding acrylic produce slightly different properties. Cast acrylic is more difficult to bend and shape versus extruded. In heat bending and thermoforming, extruded acrylic may behave differently depending on the bending direction relative to the extrusion direction. This is not an issue with cast acrylic. When colored cast acrylic is heated for thermoforming or heat bending, the color may change. Matte-colored surfaces can become clear and clear surfaces can become matte or opaque. In addition, the shade of color may change. Laser engraving should only be done on cast acrylic to produce a clear engraved image. In laser cutting, extruded acrylic will have a rougher edge, whereas cast is generally smooth. Cast is more difficult to flame polish versus extruded. Extruded acrylic tends to be more consistent in sheet thickness, while cast can vary as much as +/- 15% in thinner sizes. Cast acrylic is more resistant to the same solvents, as well more resistant to scratching versus extruded.

Acrylic applications are infinitely broad. Here are a few common examples:

Well protected and not bad for the price. Pretty much opaque with just a small amount of light let through.

Arrived fast and in good condition. Always a pleasure to go through Interstate Plastics. The Acrylic 2157 is VERY dark, but it will let light through. Luckily I picked up one of the acrylic sample packs before buying. Quite helpful.
